Abstract
Изобретение относитс к области измерительной техники, может быть использовано дл контрол работы компрессоров в газотурбинных установках и позвол ет повысить точность измерени скорости изменени давлени путем уменьшени методической погрешности пьезоэлектрического дифференциатора. Дл этого сигнал, снимаемый с дифференциатора 1, после усилени усилителем 2 вторично дифференцируют при помощи второго дифференциатора 3, умножают при помощи умножител 4 на масштабный коэффициент Τ = RC(R и C - параметры пьезодифференциатора 1) и суммируют с сигналом, полученным после усилени . 2 п.п. ф-лы, 2 ил.The invention relates to the field of measurement technology, can be used to control the operation of compressors in gas turbine installations, and improves the accuracy of measuring the rate of pressure change by reducing the methodological error of the piezoelectric differentiator. To do this, the signal taken from differentiator 1, after amplification by amplifier 2, is again differentiated using the second differentiator 3, multiplied with the multiplier 4 by the scale factor Τ = RC (R and C are the parameters of the piezodifferentiator 1) and summed with the signal obtained after amplification. 2 pp f-ly, 2 ill.
